King Charles III is celebrating his 76th birthday.
The Post hears that the royals are expected to mark Charles’ birthday with an intimate celebration this weekend at Highgrove House — the king and queen’s private residence.
“It won’t be a big affair,” a palace source tells The Post exclusively. “A normal dinner that will include a birthday cake.”
Indeed, the cancer-stricken king’s former personal butler has told The Post that “weekends are downtime for the royals.”
Grant Harrold — who worked for Charles for seven years when he was the Prince of Wales — said the royal “usually keeps his birthday quite low-key if they’re not milestones.”
“When I was there, I typically saw phone calls from the family, messages from the public, a selection of birthday cards that are put in front of him so he can see them,” Harrold added.
To mark the special day, Charles will be rolling up his sleeves and getting involved with his Coronation Food Project — an initiative he launched on his 75th birthday last year to combat food waste in the UK.
The king will cut the ribbon to open a new food bank that is hosting a “food festival” on Thursday, with meals cooked with produce that would have otherwise gone to waste. While there, Charles will also install an industrial freezer.
It’s unclear if Queen Camilla will join her husband at the event after she was forced to pull the plug on several royal engagements following a chest infection.
The royal family’s official X account shared a sweet tribute on Thursday to mark the monarch’s special day.
“🎂 Wishing His Majesty The King a very Happy Birthday today,” the post read, alongside a photo of the king donning a navy suit atop a crisp white shirt and blue tie.
The Prince and Princess of Wales also shared a birthday message on their own X account, writing, “Wishing a very Happy Birthday to His Majesty The King,” alongside a snap of Charles during his recent visit to Australia.
It’s understood that Charles’ youngest son, Prince Harry, has yet to reach out.
